I have 12 ferrets and 1 cat. Would this or the regular kennel light scent formula be better? I also have sensitivities to strong perfumes...

Answer by Chewy • Jun 18, 2019
This product is formulated with perfume if you're sensitivities smells it's recommended to use the light scent formula.

I have foster cats, a Husky and now my son's dog - a Lab. On days when everyone has to stay in due to bad weather, too hot, too cold, snow, rain...kitty boxes get a workout. This product has saved my home. The scent is very fresh and clean. My Vet actually recommended this product and now I know why.

This spray really works.

Thornell concentrate in a spray bottle gets rid of litter box odors from our two cats and keeps the surrounding air smelling fresh. Only a pump or two is required

Thornell concentrate in a spray bottle gets rid of litter box odors from our two cats and keeps the surrounding air smelling fresh. Only a pump or two is required. Also one of our cats occasionally has seizures that result in temporary loss of bladder control. The soaker bottle of Thornell works great for bigger urine spots on bedding.

This is the best product I have ever used to remove cat urine odor. I wipe the crates and litter boxes with it, and put in a spray bottle for fabric/carpet. Badly soaked areas need resprayed periodically, but it keeps the odor away for a good while. And it has a fresh smell - no overpowering.
